I've had basic facts about mathematics which are wrong deleted in revisions by editors with no knowledge of the subject beyond having asked ChatGPT (which repeats the wrong shit on Wikipedia). It's hard to be worth it. Wikipedia's biggest problem is the editors.
Wikipedia is really, really bad at mathematics. The tone is all over the place, from “plagiarized from an undergrad textbook” to “crackpot with an axe to grind against Cantor.”

Interesting. Do you have an example? I'll go look!
